SPHERICAL VS. ASPHERIC LENSES

HOW THEY’RE USED IN IMAGING APPLICATIONS

Optical Lenses are often categorized by their shape. Two common surface shapes are spherical and aspherical. Each offers unique characteristics that make it suitable for different use cases.


A filter which controls the spectral composition of transmitted energy by interference. Such filters, typically constructed of thin alternating layers of metals and dielectrics, are also known as narrowband or broadband bandpass filters.
